About Blue Topaz
Topaz is an aluminum silicate fluoride hydroxide crystal.

The name topaz comes from topazos, an ancient Greek word meaning “to seek”. This could explain the association of the gemstone with truth and forgiveness, clarity of thought and expression, and the attainment of confidence to fulfill aspirations.

Whilst yellow topaz is seen as a fire stone, connected to both Jupiter and the Sun in ancient cultures, blue topaz is thought to have lunar associations. Naturally low refraction can result in brilliance and dullness within the same stone when viewed from different angles, believed to encapsulate the waxing and waning of the moon.

Natural light blue topaz is the state gemstone of Texas, USA.

Colour
Naturally occurring blue topaz tends towards quite pale tones. The darker, more vivid blue shades of Sky Blue Topaz, Swiss Blue Topaz and London Blue Topaz are created by heat-treating yellow topaz.

London Blue Topaz has the darkest tone, often described as inky or steely.
